b TO A'LL WHOM IT MAY CONCERN: 1

Be it known that I, WILLIAM D. BROWN, of the city and county of Milwaukee, and State of Wisconsin, have invented a new and useful Improvement in Flexible Bottle-Stopples and Couplings; and I do hereby declare thatthc following is a full, clear, and exact description thereof, which will enable those skilled in the a-rt to make and use the same, reference being had to the accompanying drawing, forming part of this specica tion, in which- I Figurevl -shows a flexible coupling, with bottle and glass tube in perspective. Figure 2,'a sectional view of'same. Figure 3, a sectional view of a iiexible stopple closing the neck of a bottle. Figure 4, cross-section of bottle-neck coupling and 'glass tube Figure 5, cross-section of bottle neck and flexible stopple. Similar lettersof reference in each of the figures indicate corresponding parts. The object of my improvement is to make a flexible stopple for glass bottles, and a exible coupling to connect bottles to glass or'other tubeswhich shall close the openin'g of a bottle perfectly tight, and prevent i the passage of air, gas, or liquid without the use of wax or any'sticky substance, and thus supersede the use of ground glass stopples in moet if not all cases. When -used for coupling it makes a perfectly tight flexible x A joint. It is made of rubber, or any similar elastic material sufficiently llxiblc for the purpose. i

A lis a glass bottle; B, glass tube; C, flexible coupling; D, flange or flap fitting over the neck of the bottle to make a perfectly tight joint; E, solid exible stopple; F, ange or flap of same fitting over the bottle neck to make a perfectlyv tight joint, and to prevent the stopple from beingthrown out by the pressure of gases inside tliebottle.

What I claim as my invention, and desire to secure by Letters Patent, is- 1. Bottle A, tube B, and coupling C, in combination substantially as and for the purpose described. i 2. Coupling C when made with ilange or Hap D, as described. 3. Flexible stopple E, when made with flange or flap F, substantially as described.
